<P>PROBLEM TO BE SOLVED: To provide an air filter medium for an air processor having high air permeability and excellent function restorability by cleaning. <P>SOLUTION: The air filter medium 1 for the air processor has a PTFE porous membrane 2 subjected to oil repellent processing and an air permeable support 3. The air permeability of the air filter medium 1 is in the range of 10 cm<SP POS="POST">3</SP>/cm<SP POS="POST">2</SP>/s to 100 cm<SP POS="POST">3</SP>/cm<SP POS="POST">2</SP>/s shown by a fragile number. Further, in the air filter medium 1, the fragile number measured after a regeneration test is 90% or more of the fragile number measured before the regeneration test when the regeneration test is carried out in which air in a measuring container specified by JEM-1467 where 40 lit cigarettes are set is passed through from the PTFE porous membrane 2 side at 2m<SP POS="POST">3</SP>/min for 30 min. and thereafter the air filter member is cleaned while being submerged into a warm water upon being sprayed with detergent. <P>COPYRIGHT: (C)2012,JPO&INPIT |
